The answer to this question should be True. The perpendicular bisector, by definition, is the midpoint between two points that forms a right angle with them. It must be equidistant from R and S in order to be a perpendicular bisector.
Answer:
Step-by-step explanation:
Equation to remember:
where t = time
= 1200 since that's the initial population
= .35 rate of change \\
= 5 years
Plug in the numbers;
Since the prompt looks like it's asking for an equation given any number of years.. then just change 5 to n for number of years.
Equation of a circle that has a center at (h,k) and radius of r is
(x-h)²+(y-k)²=r²
so
given center (-1,2)
(x-(-1))²+(y-2)²=r²
(x+1)²+(y-2)²=r²
sub the other point to find r or r²
it passes through (2,-2)
sub 2 for x and -2 for y
(2+1)²+(-2-2)²=r²
(3)²+(-4)²=r²
9+16=r²
25=r²
5=r
the equation is
(x+1)²+(y-2)²=5²
